NEWSNGR reports that the warning was contained in NiMet’s Tuesday Weather Outlook for June 30.

The agency said sustained rainfall across the southern region could trigger flash floods in coastal and low-lying communities, particularly in Lagos and other states along Nigeria’s southern coastline.

NiMet forecast thunderstorms accompanied by light rainfall over parts of Ondo, Ogun, Edo, Lagos, Rivers, Delta, Bayelsa, Cross River and Akwa Ibom states in the morning.

It added that rainfall would intensify later in the day, with moderate rainfall expected across the entire southern region during the afternoon and evening.

“Southern States: Wet Morning, Heavy Rain Later. Morning: Thunderstorms accompanied by light rainfall are expected over parts of Ondo, Ogun, Edo, Lagos, Rivers, Delta, Bayelsa, Cross River, and Akwa Ibom States,” the agency said.

“Afternoon/Evening: Moderate rainfall is expected across the entire Southern region, with a high likelihood of flash flooding in coastal areas, especially Ogun, Ondo, Lagos, Rivers, Bayelsa, Delta, Cross River, and Akwa Ibom States.”

For the northern region, NiMet forecasts morning thunderstorms with moderate rainfall over parts of Borno, Adamawa and Taraba states.

The agency said thunderstorms were also expected later in the day over parts of Bauchi, Kano, Jigawa, Katsina, Zamfara, Kaduna, Sokoto, Yobe, Gombe and Kebbi states.

It urged residents in affected areas to monitor weather conditions and remain alert as rainfall intensifies.

Across the North Central region, NiMet predicted predominantly cloudy conditions in the morning.

It said there were chances of thunderstorms accompanied by light rainfall over parts of the Federal Capital Territory, Nasarawa and Benue states.

According to the agency, thunderstorms with moderate rainfall are expected across the region during the afternoon and evening.

NiMet advised residents to exercise caution, warning that strong winds could precede thunderstorms.

The agency urged motorists to drive carefully during rainfall and periods of poor visibility.

It also warned residents against driving or walking through floodwaters and advised them not to take shelter under tall trees during thunderstorms because of the risk of lightning strikes.
